High-density development of logistics warehousing racks

With the continuous deepening of urbanization, the problem of land scarcity is becoming increasingly serious. Warehousing and logistics land, which is indispensable in industry, commerce, and society, is also becoming increasingly scarce. High-density warehouse logistics technology has become the current development trend.

On the one hand, traditional warehouse racks are being built higher and higher. The current high-rise storage racks even exceed 40 floors, which is conducive to making full use of rack warehouse space. On the other hand, this is conducive to reducing the number of lanes and realizing the horizontal and vertical placement of goods. High-density storage in the direction.

Common types of warehouse rack:

Drive through racks and drive in racks:

Forklifts can drive into drive through racks or drive in racks to access goods, which reduces the passages required for forklifts and can further save warehouse space so that more racks can be put down, greatly improving the space utilization and storage capacity of the warehouse. , the drive through racks have passages on both sides, which can implement the first-in, first-out strategy, while the drive in racks are only equipped with one-sided passages, so they can only implement the last-in, first-out storage strategy.

Push back racks:

The push back racks are used in conjunction with the cargo trolley. The palletized goods are pushed into the storage racks one by one by the cargo trolley. When the goods on the first cargo space are taken away, the goods on the next rack will be automatically returned to the first cargo. In this type of warehouse racking system, the forklift does not have to drive into the storage lane, the operation efficiency is high, and only the last-in-first-out storage strategy can be realized.

Gravity racks:

Gravity is used to realize the storage and retrieval of goods. Gravity racks mainly arrange unpowered rollers in the storage lanes and install them at a small downward angle. The goods rely on their weight to automatically enter the storage end and slide to the lower shipping end. After the first cargo is taken away, the cargo in the next cargo space will be automatically put into place, realizing first-in, first-out.

Radio shuttle racks

The pallet radio shuttle rack storage system is a semi-automated warehousing technology. Different from the drive through racks and drive in racks, the forklift does not have to enter the rack lane to operate. Instead, it cooperates with the pallet shuttle to operate on the aisle, which greatly reduces the cost. The accident rate of forklifts hitting storage racks can be increased accordingly, and the length of the lane can be increased accordingly to further increase the density of storage.
